Help cutting open 40ft reefer, we now have problems

[Gary]

Gary all the condensers are at the back of the containers at present 3 in total 1 in each of the 40's and one in the 20.

By "the back" I assume you mean the end of the container furthest from the Kingspan doors. Is this correct?

We will be adding an additional one in the cool space.

This should also be placed at the back, up high, away from those doors. As noted previously by Electrocoolman, hot air rises and cold air falls... and we don't want to blow cold air out the door.

The doors are not actually that high, we have since lowered them to approx half the height shown on the sketch.

You may also want to limit how wide they open.

I agree about the U-shape, this is what i started with originally but someone decided to change this. the 40foot storage container is an insulated 40ft container just used to help raise the height of the cool space.

A place to store Xmas decorations.
